History Characters / RodAllbrightAlienAdventures

* ExtraEyes: He has a third eye above the normal two. It doesn't five him extra powers though.

* OmnicidalManiac: He tries to destroy the universe ''twice'', first by making it [[WhenDimensionsCollide merge with Dimension X,]] and later by [[TimeStandStill permanently freezing time.]]

* MoralDissonance: In ''I Left My Sneakers In Dimension X'' he [[KickTheDog deliberately tricks Elspeth into eating some of the horrible tasting food they are given when imprisoned in Castle Chaos]], due to him being upset about her expressing concerns that the food might be unsafe for human consumption and could do something horrible to their insides. We're meant to see her as deserving it, but, as she was just being ProperlyParanoid, it just makes Rod seem like a dick.

* JerkWithAHeartOfGold: She may be a pretty big brat, but she ''does'' care about Rod and they eventually become FireForgedFriends after all they go through. Rod even says in one book that she's like broccoli: you can learn to like her.

* TemporaryBulkChange: As seen in ''Aliens Stole My Body'', Edgar can apparently swell up to incredibly large proportions when he's well-fed. He shrinks back to normal as he beams that energy into Seymour.

* AlienBlood: The one time he's hurt enough, he leaks a purple fluid from his wound.

* PutOnABus: His last appearance is having a short talk with Rod on the way to school in the opening of ''I Left My Sneakers in Dimension X'', and is never seen again for the rest of the series. Justified in that summer vacation started a few weeks later, and Rod went off-planet for most of that time.

* CannotTellALie: For traumatic reasons, he starts the first book pathologically honest. Frustratingly, [[CassandraTruth it never works in his favor later on]]. [[spoiler: He eventually overcomes this in an attempt to mislead the main villain, but even then it gets seen through immediately.]]

* HalfHumanHybrid: It turns out his father's disappearance is more complicated than it seemed. [[spoiler: He is actually still fully human, but his father's side of the family is from [[{{Atlantis}} a different sprig of the human tree...]]]]

* TookALevelInBadass: At the start of the first book, Rod is a likable and good-hearted kid, but also kinda fat and a bit of a loser. By the end of the final book, he's a disciple of warrior science ''and'' Mentat skills, he defeats all the villain's henchmen on his own with cool-headed decision making, and he plans to return to the stars someday.

* HalfHumanHybrid: Much like Rod.

* DaddyHadAGoodReasonForAbandoningYou: Unfortunately for everyone else involved, BKR was too clever to be fully tricked, and had good reason to lie low in a galactic backwater anyway.

* NeuroVault: He has a secret that will let BKR destroy time itself, and, because he feels his own mind is not secure enough, [[spoiler: he stashes it in his son's. This comes back to bite both of them.]]

Rod's sixth-grade teacher.

* IAmAHumanitarian: He doesn't ''actually'' eat the human characters, since he's an ultimately good figure, but he can't help drooling because he finds them really, ''really'' delicious looking.

* MoralDissonance: In ''I Left My Sneakers In Dimension X' He [[KickTheDog deliberately tricks Elspeth into eating some of the horrible tasting food they are given when imprisoned in Castle Chaos]], due to him being upset about her expressing concerns that the food might be unsafe for human consumption and could do something horrible to their insides. We're meant to see her as deserving it, but, as she was just being ProperlyParanoid, it just makes Rod seem like a dick.

* GlamorousSingleMother: Played with. Raising her kids for three years alone is noted to be hard on her, and the family doesn't have much money (which is a plot point when a well-heeled bully's family threatens to sue), but she is holding things together.
* WidowWoman: The disappearance of Rod's father hit her very hard. She puts on a brave face for her children, but sometimes cries in her alone time.

* BeenThereShapedHistory: Not on Earth, really, but he is the Ferkada who founded the school of the Mentats.

Seymour is one half of the Chibling that Rod bonded to in Dimension X, which split into a two-part creature upon reaching maturity. His most prominent feature is his head: a single enormous eyeball about the size of Rod's fist and sheathed in blue skin. Seymour's body resembles that of a "squashed, ridged, naked blue cat", but with six legs (originally four, all ending in two blobby, clawless toes), and a snaky blue neck and tail. His brain is in his torso, and he has a psychic connection to Rod's brain (a quirk of his species). He also breathes through his skin.

Edgar, the other half, still resembles their original form: a purple furball about a foot and a half long, with several pairs of legs and two large, black eyes. Except for being purple, he looks a lot like a caterpillar. Edgar does the eating for the two, beaming energy into Seymour via the latter's eye.

* SuperDrowningSkills: Since Seymour breathes through his skin, he starts to suffocate once he's underwater - a fact he and Rod learn the hard way on Kryndamar.
* VertebrateWithExtraLimbs: In ''Aliens Stole My Body'', Seymour is suddenly identified as having six legs (he only had four in ''The Search for Snout'').

* FarmBoy: He grew up in a swamp on a "worm farm." His family was actually very successful too (he mentions being able to experience other worlds in a VR tank they owned), but he still wanted to go out and see the universe.
* FireForgedFriends: At school, he originally admired BKR's genius and charisma, and saw Snout as an effete loser. But, when their common discovery of BKR's cruelty united them, they became first allies, then incredibly close friends, such that they share a cabin on the ship where everyone else has their own accommodations, and their bond with one another allows Snout to track him wherever he goes.

* PersonalityChip: Downplayed in all later installments, but "personality modules" that alter his thinking play a key part in the first book. Madame Pong switches them out from time to time. He spends most of the novel wearing a Diplomatic Module, which clashes so heavily with his natural personality that Madame Pong complains that he keeps burning them out, and proves largely-ineffective at restraining him, a Docility Module, which [[GoneHorriblyRight works too well]] and turns him lazy and calm even in situations where action is required, and the Berserk Module, which reduces his intelligence and leaves him using HulkSpeak but also makes him incredibly fierce and wild. The later books mention a Battle Module, which Tar Gibbons feels was poorly programmed, a Judicial Module for when he needs to discipline Elspeth after she stows away on the ''Ferkel'' in book 3, and an "Open Mind" Module.

Master of the Martial Arts and "Warrior Scientist," it takes Rod as its student in ''I Left My Sneakers In Dimension X''.

* ItIsDehumanizing: Averted. It is neither male nor female, and thus prefers to be called by "it" than by "he" or "she". Rod points out that this is very awkward given the language they're using, and the Tar agrees, but insists that it is less offensive than calling it "he" or "she" would be.

* TheMole: The Ting Wongovia's spy within Smorkus Flinders' organization.

* VoluntaryShapeshifting: All of his kind are capable of this. It's an evolutionary response to one of the dangers of Dimension X - as he puts it, "When you can change your shape at will, a Reality Quake doesn't make that much difference to you."

* ImmortalityBeginsAtTwenty: His biological age (as opposed to his ''actual'' age, which is measured in millenia) is elderly for a pure human. Art puts it down to a mixture of long-term suspended animation having some side effects that slow his aging, and the advanced medical science of the rest of the galaxy.

BKR's closest friend, originating from Dimension X, is known across six dimensions for his cruelty. This is why he and BKR get along so well.

* MoralDissonance: In ''I Left My Sneakers In Dimension X' He [[KickTheDog deliberately tricks Elspeth into eating some of the horrible tasting food they are given when imprisoned in Castle Chaos, due to him being upset about her expressing concerns that the food might be unsafe for human consumption and could do something horrible to their insides. We're meant to see her as deserving it, but, as she was just being ProperlyParanoid, it just makes Rod seem like a dick.

* FantasticHonorifics: The "Tar" means, roughly, "wise and beloved warrior who could kill me with his little finger if he so wished."
* ItIsDehumanizing: It is neither male nor female, and thus prefers to be called by "it" than by "he" or "she".

* GoodCannotComprehendEvil: He admits that the only reason it took him so long to figure out the connection between Art and Rod is that he never in a million years expected the brilliant and enlightened scientist and time-traveler he knew to marry a good woman and settle down to live a happy life with a family.

* TopHeavyGuy: Downplayed, but his physique is enormously muscular and powerfully built, by human standards.

* FormerlyFat: He starts the first book kind of pudgy, but hard work and studying warrior science helps him get into shape by the end.
* HalfHumanHybrid: It turns out his father's disappearance is more complicated than it seemed. [[spoiler: He is actually still fully human, but his father's side of the family is from [[{{Atlantis}} a different sprig of the human tree...]]

* BodyBackupDrive: When the villains take Rod's body, Seymour uses his connection to Rod to store Rod's mind, including whatever secret is stashed there, inside portions of his own massive brain until it can be retrieved.

* PersonalityChip: Downplayed in all later installments, but "personality modules" that alter his thinking play a key part in the first book. Madame Pong switches them out from time to time. He spends most of the novel wearing a Diplomacy Module, which clashes so heavily with his natural personality that Madame Pong complains that he keeps burning them out, and proves largely-ineffective at restraining him, a Passivity Module, which [[GoneHorriblyRight works too well]] and turns him lazy and calm even in situations where action is required, and the Berserk Module, which reduces his intelligence and leaves him using HulkSpeak but also makes him incredibly fierce and wild.

* ItIsDehumanizing: It prefers to be called by "it" than by "he" or "she."

A Shapeshifter from Dimension X, he provides aid to the crew and leads them to the Ting Wongovia.

Master of the Martial Arts, it takes Rod as its student in ''I Left My Sneakers In Dimension X''.

Master of the Martial Arts, he takes Rod as his student in ''I Left My Sneakers In Dimension X''.

The ship's science officer and chief pilot. He resembles a large sunflower.

* PlantAliens

* NoSell: When the rest of the crew is knocked out by an airborne gas, Quince is completely unaffected, stating that "That stuff doesn't work so well on someone who's breathing water."

Rod's fraternal twin siblings, three years old at the start of the series. (Linda was born first.) They started going by the nicknames "Little Thing One" and "Little Thing Two", respectively, after Rod read ''Literature/TheCatInTheHat'' to them.

Mother of Rod, Linda and Eric, wife of Arthur "Art" Allbright. Her father is a farmer who lives nearby.

Father of Rod, Linda and Eric, husband of Jean Allbright. Actually a semi-alien from ancient Atlantis and founder of the Mentat under the identity "the Ferkada". He had at least one younger brother, Kah-nath.

The ship's Mental Officer, possessing various psychic powers.

A member of the same species as Quat, he was part of BKR's crew on the ''Merkel''.

Rod's best friend on Earth, he has one younger sister, Markie.

A fat, white-skinned alien with green hair and red teeth, who works as an exotic pet trader and has a brain-worm (which lives in his nose and stimulates his brain's activity) as his own pet. vacationing on the planet Kryndamar when Rod and his allies are in hiding there, he reluctantly helps them get back to Earth.
